In Japan, the maximum speed of meter-gauged railway lines (conventional lines) is 160km/h. In recent years, the overhead contact line with a feeder messenger wire, which has the features of labor-saving maintenance and construction cost reduction, has attracted attention. Because further high-speed performance is required, even for meter-gauged railway lines, the development of the overhead contact line with a feeder messenger wire that has excellent high-speed performance is desired. Therefore, compound catenary equipment with a feeder messenger wire has been developed for meter-gauged railway lines. This overhead contact line enables a train to operate at a speed of 160km/h and maintain the features of labor-saving maintenance and construction cost reduction. We performed theoretical analyses and a dynamic-characteristic evaluation to confirm the validity of the overhead contact line. Moreover, we conducted a test run to verify the current collection performance of the overhead contact line.
